Mr. Smith creates a new sauce because he wants to increase his restaurant’s sales by creating a burger that reduces gas producti

on. He recruits 100 customers with a history of gas problems. He has 50 of them eat burgers with the new sauce. The other 50 eat burgers with sauce that looks just like the new sauce, but it is really just a mixture of mayonnaise and food coloring. Both groups were told that they were getting the new sauce. Mr. Smith has all of the participants track their production of gas for 24 hours. Mr. Smith finds that customers who ate the new sauce had less gas production for 24 hours.

Iodine-131 is administered orally in the form of NaI(aq) as a treatment for thyroid cancer. The half-life of iodine-131 is 8.04
evablogger [386]

Answer:

16.6 mg

Explanation:

Step 1: Calculate the rate constant (k) for Iodine-131 decay

We know the half-life is t1/2 = 8.04 day. We can calculate the rate constant using the following expression.

k = ln2 / t1/2 = ln2 / 8.04 day = 0.0862 day⁻¹

Step 2: Calculate the mass of iodine after 8.52 days

Iodine-131 decays following first-order kinetics. Given the initial mass (I₀ = 34.7 mg) and the time elapsed (t = 8.52 day), we can calculate the mass of iodine-131 using the following expression.

ln I = ln I₀ - k × t

ln I = ln 34.7 - 0.0862 day⁻¹ × 8.52 day

I = 16.6 mg

The equilibrium constant for the reaction: HCHO(g) ⇌ H2(g) + CO(g).
tiny-mole [99]

Answer:

K = [H2] [CO] / [HCHO]

Explanation:

HCHO(g) ⇌ H2(g) + CO(g)

We can obtain the expression for the equilibrium constant for the above equation as follow:

Equilibrium constant, K for a given reaction is the ratio of the concentration of the product raised to their coefficient to the concentration of the reactant raised to their coefficient.

Thus, the equilibrium constant, K for the above equation can be written as follow:

K = [H2] [CO] / [HCHO]

How might you estimate the minimum temperature
bixtya [17]
To estimate for the minimum temperature of a daily forecast of low temperature, the first estimate would be the dew point temperature approximately an hour before the daily high temperature is reached. I hope this helps you on your assignment.
